When it comes to dog bark control, ultrasonic bark control devices are one of the most popular methods. This ultrasonic bark control device uses ultrasonic technology and is a safe and effective training tool. The effect of the product is not only related to a dog breed, dog age, hearing sensitivity, but also closely related to whether the owner uses the product correctly. When the dog has bad behavior, you can press the start button. When the dog stops the bad behavior, you stop releg the ultrasound. At the same time, you need to use an ultrasonic trainer in conjunction with the command requirements or appropriate action guidance. In order to achieve the desired results, once your dog accepts the ultrasonic bark controller correction and stops barking, you can give the pet appropriate rewards, such as snacks, petting, etc., to actively guide and strengthen the dog's memory. The dog will eventually learn to associate the barking with the ultrasound, forming a conditioned reflex and will stop barking this behavior. The conditioned reflex of the dog usually takes 3-10 days to form, adapt and consolidate. During this period, the owner should continue to train the dog patiently.
